Conversion of sunlight to chemical fuels by artificial photosynthesis has been a long-sought goal. The major goal of the proposed effort is to develop a novel fuel-generating (e.g., hydrogen) photolytic device, which consists of a semiconductor nanowire decorated with metal nanoparticles. The project targets a low-cost technology by fabricating and utilizing the nanowire-nanoparticle conjugate de ...

Antimony containing III-V semiconducting compounds are particularly attractive for the fabrication of a wide variety of electronic and optoelectronic devices such as photo detectors operating in the long wave infrared wavelength (12-32µm) range. The production of epi quality GaSb wafers still remains one of the important problems for rapid commercialization of GaSb devices. Sinmat Inc. proposes a ...

A mathematical framework for detection and classification of weak, distributed patterns on computer networks is proposed. The framework will provide rigorous methods for understanding performance bounds and optimality of intrusion detection methods, while also providing concrete and implementable algorithms. The algorithms will find immediate application in cyber-security efforts, as well as mor ...

In miniature gas turbines for UAV applications, traditional bearings exhibit a typical lifetime of only 25 hours due to excessive axial loading. Mainstream proposes to use a passive, permanent magnet thrust bearing to alleviate this problem and increase service life to over 1000 hours. Since this type of bearing is non-contacting, it can operate at very high rotational speeds with minimal heat gen ...

The objective of the proposed research is to develop a portable, passive system for rapid and efficient blood component separation. While a number of macro-scale devices are routinely employed in laboratory settings to separate, for example, red blood cells (RBCs) from platelet-rich plasma (PRP), and an emerging class of microfabricated devices are slowly being developed to address various low-th ...

We will develop novel acousto-optic devices for use in the UV using the new material Barium Borate (BBO) which not only has the required UV transparency, but a unique combination of acoustic and optical properties. The capabilities provided by these new UV AO devices are ideally suited for optical addressing arrays of trapped ions with focused spots from appropriately tuned UV and visible lasers t ...

Space surveillance is the component of space situational awareness focused on the detection of resident space objects (RSOs) and the use of multisource data to track and identify space objects. While the propagation of the states of RSOs has been investigated extensively over the last fifty years, the correct propagation of their covariance or the more general (non-Gaussian) probability distribut ...

DESCRIPTION (provided by applicant): This Phase 1 STTR application seeks support for research to enhance the commercial viability of a tool to assess the cultural competence of health care organizations. The tool was developed by Dr. Thomas A. LaVeist, who is director of the Hopkins Center for Health Disparities Solutions at the Johns Hopkins Bloomberg School of Public Health. The Cultural-comp ...

Hydrogen produced today from coal, natural gas, or biomass must be separated and purified outside the reactors using pressure swing absorption (PSA), a process that requires significant additional space and energy. Placing hydrogen-permeable membranes inside the reactors themselves would allow hydrogen to diffuse out, thereby reducing the cost of hydrogen production. In this Phase I effort, Mainst ...

This Phase I STTR program seeks a new fabrication method to produce stronger (>100 kpsi) and tougher (>10 MPa m1/2) ultra high temperature Ta-Hf-C-based composites (UHTC) with an outstanding oxidation resistance for use as thermal protection systems for hypersonic applications, as well as for advanced rocket nozzle throat components. UES will apply a novel "Top Down" approach to control the micro ...
